That is it. Now, to apply the oil you can use any of the following; q-tip(any part), soft cloth (any part), rough cloth (everything but decals), steel wool (or synthetic steel wool also known as green or blue scrubbies)(metal parts ONLY), wire brush (brass is best)(metal parts ONLY)
Apply the oil, give it some time to soften the old oil (what you see there that looks like resin) and then wipe/brush clean
If you REALLY need to have the metal parts shine, after using the oil to clean it you can use Brasso to polish it (Non-abrasive)
just my .02
